On linux, you can control this behavior with the setgid mode bit on the
parent directory. Does that also work on OSX?

We sometimes get an error say "well-known file is not secure" when
running attach-tests on mac osx. The reason is a difference in how
files are created between linux and mac osx (and that the mac code in
HotSpot originates from the linux code):
* On linux, the default group owner of a newly created file will be
user's effective group (id -g).
* On macos, the default group owner of a newly created file will be
group owner of the directory the file is in.
The attach framework will verify that the file has the same effective
owner and group as the currently running process. This will be true on
linux, since files are created with the effective user and group as
owner. This will NOT be true always on macos, since the file can have
a different group if the temporary directory has a different group
than what we are currently running as.
The fix on macos is to change the group ownership of the well-known
file to the effective group when the file is created.
The fix has been verified by manually changing the effective group of
the launching user.
